Brassica rapa (narinosa group) (45 days) Open-pollinated. What grows quickly, can be seeded as late as August, withstands frost and is, according to Orlando Sentinel columnist Sherry Boas, “just as versatile as spinach”? Yes, Tatsoi, also known as Tah Tsai. In Michigan, Anne Elder has picked it all fall into December even after a snow melt. Remains sweet and unburnt by cold during mild winters. “A dream come true for snow-dwelling beings craving greens.” Spoon-shaped thick dark green leaves make beautiful compact rosettes with mild brassica flavor. Make great microgreens. Also good in place of lettuce in sandwiches, stir-fried, in quiche, lasagna or soup. Will come back when cut. An essential ingredient in our salads and mesclun. ~13,600 seeds/oz. Tested negative for BR and BL.Cold-hardy. ⑤
